Method and system of beamforming a broadband signal through a multiport network

Abstract

Aspects of a method and system for beamforming a broadband signal through a multiport network are provided. In this regard, a plurality of signals received via a plurality of antennas may be detected and a plurality of transmit signals may be generated, wherein a phase of at least one of the plurality of transmit signals is responsive to at least one of the detected phases of the received signals. Each of the generated plurality of transmit signals may be separately amplified to generate a plurality of amplified signals. A plurality of the amplified signals may be input to a plurality of first ports of a multi-port network, wherein at least one second port of the multi-port network may be responsive to signals input to at least two of the plurality of first ports.

Description

CLAIM OF PRIORITY[0001]This patent application is a continuation-in part of U.S. patent application Ser. No. 12 / 689,058 filed on Jan. 18, 2010. This patent application also makes reference to, claims priority to and claims benefit from U.S. Provisional Patent Application Ser. No. 61 / 302,214 filed on Feb. 8, 2010.[0002]Each of the above stated application is hereby incorporated herein by reference in its entirety.FIELD OF THE DESCRIBED EMBODIMENTS[0003]The described embodiments relate generally to wireless communications. More particularly, the described embodiments relate to methods and systems for beamforming a broadband signal through a multiport network.BACKGROUND[0004]Conventional wireless subscriber stations employ radio-frequency (RF) transmitters to produce an output signal that is transmitted to the base station (BS). In mobile wireless networks, one station may be a mobile station (MS), whereas another station may be a BS (BS). As the MS moves throughout the coverage area o...

Problems solved by technology

However, it is not generally feasible to equip an MS with an arbitrarily high-power amplifier for several reasons: (i) there is a limit on the total power that may be consumed by the device; (ii) a high-power amplifier may get excessively warm; (iii) a high-power amplifier may be expensive; (iv) a high-power amplifier may be too large to fit within the size constraints of a small mobile terminal; (v) a high power amplifier may exceed specific absorption rate limits designed to protect safety.
